Using Comet Ice to Fight Global Warming!

Celesita... its awesome!

Molecular visualisation using VMD... also free n awesome!

Dropping comet ice into the ocean to cool it sounds like a kindergarten level understanding of science.

[wdmm]

Not to mention it would raise sea level. People will give this serious discussion but won't talk about building a nuclear power plant.

Fun Fact: A day was 28 hours long in Futurama because so much mass had been added to earth from the ice cubes and alien spaceships that it slowed earth's rotation.

As Randall Munroe said, "it's honestly sort of impressive to find a solution that would actively make the problem worse in so many different ways."

[raymccrae]

Glad you included the futurama clip, because that was literally my first thought when I read the video title.

[Codexionyx]

Randall Munroe wrote a What If? article on this exact thing - and went through the same problems - some time ago, and came to the conclusion that it was like plugging a bottle of overflowing diet coke with a mentos.

Seems like an apt metaphor for a lot of things.

We just need to somehow capture the water from thin air and freeze it using energy from solar roads. Its quite simple its like playing air hockey really.

My first thought on seeing the title was of that Futurama episode, I'm so glad you referenced it.

[interstellarsurfer]

I love that Matt is finally getting the respect he deserves. 🤣

[leamaelgamer]

Don't we all love that elusive group of "some scientist"...

[boathemian]

I’d much more likely trust Will Ferrell’s understanding of physics than Matt Ferrell

[rhouser]

Remember the Hovind theory? Comets hit the earth freezing Mammoths with food in their mouth…Pretty sure this is the same thought

[gavros]

Randal Munroe did it first on his blog, although he went more into the fact comets would make global warming worse since they contain CO2.

[fleetkidn]

Asking Sub-Zero to chill the ocean sounds more logical.

[Tajarim]

Dinosaur scientist 1 to Dinosaur scientist 2: "Of course I'm sure about pulling that thing down towards earth, what could possibly go wrong?"

[jercos]

The fact that one Halley's comet per year is a meaningful number (assuming sci-fi magic spaceships) makes me think Futurama's writers once again, in fact, did the research.

[DisFuntastic]

What a relief, finally a video again on different and more interesting topics I so much enjoy. Thanks TF!

Colliding water droplets has never been so entertaining. (And educational)

[shadeblackwolf]

So to do this, drop comet ice into the ocean for cooling, we need to slow it down to low earth orbit so we can handle it, then send it down in chunks with plenty heat shielding, then drop it once it's landed.... sounds like more heat emissions than the ice could ever cool

[orbatos]

Great explanation as usual and the relative velocity perspective is particularly educational for those unfamiliar with the concept.
